2107554 9217809 PCTABS00016 A polygon (P7) having a radius which is correlated to a tracking radius by a rule which creates an improved linear tracking system with a constant optical path. The polygon is useful for reading and writing information, and tracking industrial products on a rotating carousel. When the polygon is mounted on the center (R13) of a rotating carousel (C1) with no relative movement therebetween, it can perform accurate linear tracking of objects located on the carousel. The radius of the polygon is equal to half the tracking radius divided by the cosine of an angle of 180/n where n is integer. The polygon can have an arbitrary number of sides. Using another method, the non-linearity of the system for an arbitrary polygon's radius can be corrected by a series of sensors (N1 to N4) positioned at non-linear intervals to trigger a laser beam, creating an effective linear movement of the laser beam on the tracking circumference of scanned objects.
